摘要：
Tb-Fe-Co/Co-Cr-Pt-B hybrid media with various Tb-Fe-Co thicknesses were prepared in order to investigate high-density recording characteristics and thermal decay. As a result, the magnetic cluster size of hybrid media increased in proportion to the Tb-Fe-Co thickness. The hybrid media with 7.5 nm thickness of Tb-Fe-Co showed the highest signal-to-noise ratio and low thermal decay. (C) 2004 Elsevier B.V. All rights reserved.
